Mrs. smith runs a dessert parlor. their top selling items are waffles and milkshakes. she sells waffles for $5 each and milkshakes for $3 each. mrs. smith want to sell at least 60 waffles and milkshakes in all and wants to earn at least $210. if each waffle takes 7 minutes to make and each milkshake takes 3 minutes to make, how many waffles and milkshakes should she make to minimize the time spent making the two items?

75%

step-by-step explanation:

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
